Considering the cleft group, there is a tendency for the maxillary sinus volume of the cleft side to be smaller than its contralateral (P<0.001). Statistically significant differences were found in the maxillary sinus volume, regarding the age and sex of cleft and noncleft patients (P<0.001 for age; P=0.001 for sex). According to these results, the presence of unilateral cleft lip and palate did not affect the maxillary sinus volume, comparing cleft and noncleft patients. A biphasic growth pattern of the maxillary sinus and a presence of sexual dimorphism were found.

This research aimed to determine whether Class II malocclusion can be treated with clear aligners after completing treatment with the initial set of aligners. A sample of 80 adult patients were divided into Group 1 with Class I molar malocclusions (n=40 [11 men and 29 women]; 38.70±15.90years) and Group 2 with Class II molar malocclusions (n=40 [11 men and 29 women]; 35.25±15.21years). All patientshad finished treatment with the initial set of Invisalign aligners (Align Technology, Santa Jose, Calif) without known centric occlusion-centric relation discrepancies, issues of compliance, or overcorrection. The 7 measurements using the American Board of Orthodontics (ABO) Model Grading System and millimetric measurements for anteroposterior (AP) and vertical dimensions were assessed and compared between the 2 groups at pretreatment, posttreatment ClinCheck (Align Technology) prediction, and posttreatment. No improvements were observed in the APcorrection. The amount of AP correction in patients with Class I. No significant Class II correction or overjet reduction was observed with elastics for an avera
